Looking at options to stay with the n52 radiator, and coolers. It’s bigger, surprised that there is a difference, but now see we’re the intercooler sits. I have all the radiators and coolers from the xi, except the module it sits in, and the ps cooler.
It seems the e60 is the black sheep in the n54 line up, the engine and trans are the only things that seem to have no issues if swapped. I have here another example, I ordered the RB heat shield and bracket. It’s a nice piece, and sits well on the engine, except the charge pipe hitting it. I also bought the VTT charge pipe before, and couldn’t use the rear pipe being it was tight up against the turbo fold. This is a pic of the shield and a the hybrid pipe I put together using the stock rear and VTT a front.
